CHARLES B. SMITH, OF PROVIDENCE, RHODE ISLAND.

SLEEVE-BUTTON.

SPECIFICATION forming part of Letters Patent No. 490,836, dated January31, 1893.

Application filed May 14, 1892. Serial No. 432,957. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES B. SMITH, of the city and county ofProvidence, in the State of Rhode Island, have invented a certain newand useful Improvement in Sleeve-Buttons; and I declare the following tobeaspecification thereof, reference being bad to the acopen orring-shaped shoe, mounted and hinged upon said post, as hereinafterparticularly specified.

In the drawings A represents the head or ornamental front of the buttonand a the lining plate thereof.

The post or shank of my improved button is, compound and consists of anouter portion 13 and an inner portion 0, the latter slidingtelescopically within the former. The portion B is made of gold-plated,seamless hollow wire and is preferably oval in cross section. Theportion 0 is solid. The outer edge of the portion B is covered by acap-piece b of corresponding shape, which serves to conceal the rawedge. In the portion B are two indentations, which, on the inner surfacethereof, form small knobs or projections c 0' (see Fig. 3), while theportion O'has two indentations or sockets d 01, corresponding in sizeand location with the knobs c c of the portion B, and between thesockets d d and from the socket d to the lower edge there is a shallowchannel or groove 6. (See Figs. 3, 6 and 7.)

A tube D, made of a section of hollow wire, preferably seamlessgold-plated, is soldered upon the outer end of the portion 0. The shoe Eis made of gold-plated seamless wire, drawn into the form shown in crosssection at min Fig. 5, having a straight inner edge, a plane base and acurved upper surface. The

into an oblong ring-shape and the" ends are soldered, as indicated at nin Figs. 1 and 4. Two lugs 5, made of small sections of wire, partiallycut away to form plane surfaces and shoulders, as seen in Fig. 5, aresoldered on said plane surfaces to the under or plane surface of theshoe E. Before the ring E is fully bent and soldered at its ends, theselugs s are sprung into the open ends of the tube D and when the ends ofthe ring arebrought together and united, the lugs and tube form ahinge-joint.

The compound post B O is extensible, as illustrated in Figs. 1 and 2 andwhen the part 0 is extended, as there shown, the shoe Ecan be turned ortilted on its hinge D s s and its edge will swing into contact with orabove the cap b of the part B. The knob c is then in frictionalengagement with the indentation d: When the button is in thisposition,the shoe E is inserted through the button hole of the cuff and then isturned to a right angle with the post. The portion 0 of the post is thenpushed down into the portion B, as seen in Fig. 3, thus shortening thepost and the knobs c c are then in engagement with the sockets d 61',respectively. In extending the post 0, the socket d is moved out ofengagement with the knob c, the channeled portion passes by said knobuntil the socket 01 comes opposite to the knob 0, when it engagestherewith. The part 0 can be provided with any suitable means to preventits entire removal from the portion B.

The advantage of an extensible post or shank is that a shoe of aconsiderably larger diameter can be used than with a fixed or permanentpost; as it affords a-greater space for the swing or tilting of theshoe: yet when the .100 as to have a rounded surface with suitableedges, all having a gold exposure, instead of being formed of a disk ofplated metal with a turned edge and requiring a separate lining plate.

I claim as a novel and useful invention and desire to secure by LettersPatent.

1. The improved button herein described Consisting of the head or frontA, the hollow post B, attached to said head A and provided with interiorknobs 0 c, the solid post 0 longitudinally movable Within the hollowpost B and provided With sockets d d and groove 8, the tube D upon theouter end of the post 0 and the ring-shaped shoe E having lugs 8,adapted to enter the ends of the tube D and to form a hinge therewith,substantially as :5

specified.

2. The combination of the head or front A, the hollow post B attachedthereto and provided with interior knobs c c, the solid post 0longitudinally movable Within the hollow post B and provided withsockets d d and groove e, the tube D upon the outer end of the post 0and a shoe, mounted and hinged upon the post 0, substantially asdescribed.
